Scratch

I posted this in the wrong place somewhere on this forum, so please forgive me if you read it before.  as it is, no one has replied.  so here i try again.  starting with:

hi...

I cannot make my things do what I want them to do today.  I'm stuck.

What I am trying to accomplish is this:

sprite1 is dragged over to sprite2 and as soon as sprite1 touches sprite2, sprite2's costume changes.  Then sprite1 can be used to change Sprite3 or Sprite4, etc.  and when it is completed then sprite1 can be dragged near where it originally was and then snap into position from there.

Is this all possible?

i'm trying to create a paint-fill simulation by changing out the costumes by actually touching them, rather than clicking on a button to change them.

it's a challenge.

thanks.

:-)

Scratch onwards....
